![]() ![]() However, the latest research shows that penis size may also be the result of sperm competition and natural selection. One might be forgiven for thinking that larger penises evolved as a result of sexual selection the theory that a preference for larger penises in females has led to greater reproductive success for males with larger penises, with these males passing on the trait to their offspring. The mystery of the human penis is that ancestral hominids lived in similarly large and promiscuous social groups, but did not evolve the large testicles seemingly necessary to compete via sperm competition. Other physically smaller males have little access to females in the group. Correspondingly, the male gorilla’s huge stature is in fact the reason why he has such a small penis: when competition between males occurs through physical aggression, an alpha male may fight off rivals and control his own mating success without the need for sperm competition. This evolutionary advantage of producing large amounts of sperm can explain the relatively large testicle size of chimpanzees. The male who produces more sperm will have the best chance of fertilizing an egg. Sperm can live for up to 4 days after ejaculation, and consequently when females mate with two males in close succession, sperm from two males can be in direct competition. ![]() Chimpanzees live in large multi-male, multi-female groups, where females are able to mate with many males. In fact, generally speaking, the mating system of a species can be used to predict penis size. So, what causes these seemingly contradictory differences among the great apes, and how can evolutionary theory make sense of all creatures great and small? Sperm CompetitionĪs Freud’s quote suggests, the clue to the evolution of the penis is not just in their physical appearance but also in the social aspects of sex. Moreover, while silverbacks are formidable looking creatures, gorillas in fact have the smallest penis to body size ratio of any mammal. It is also useful to mention some more unusual facts: firstly, while chimpanzees have penises half the size of humans, they have testicles three times as large. Despite the frequently discussed individual variation in human penis size, the shaft of an average human penis is around twice the length and width of the shaft of an average chimpanzee penis. When Sigmund Freud wrote this in 1912, he may have been surprised to hear that some hundred years later, evolutionary theory would come to the same conclusions. "So we started out looking at lizards and snakes," Tschopp says.Anatomy is destiny … The genitals themselves have not taken part in the development of the human body in the direction of beauty: they have remained animal, and thus love, too, has remained in essence just as animal as it ever was. But where did it come from? Tschopp and his colleagues thought a clue might lie in the way embryos of different animals develop. It became an essential trick for getting sperm to eggs. So nature came up with a different way: the penis. "If you go to land, your eggs would dry out if you just lay them on the ground," says Patrick Tschopp, a researcher in genetics at Harvard Medical School. That all changed when our ancestors crawled up on land. It would all mix and fertilize in the water. A female could lay eggs, and a male could just swim by and excrete some sperm. Penises weren't necessary when our early ancestors lived in the ocean. The research might also one day help illuminate a medical mystery: Birth defects of the penis have risen sharply in recent decades, and nobody is sure why. New research published this week sheds light on how the penis evolved and how it forms in different animals. Patrick Tschopp/Harvard Medical School/Department of GeneticsĮvolution has shaped every part of the body, and that includes our private parts. Researchers now believe that signals from the embryonic gut trigger the development of the penis in many different species. A python embryo turns its leg cells into a pair of penises.
